herbie and basement sump

[mark]

even with a gate valve it's very very small adjustments then need to wait few minutes between touching it. Also first time up might take a bit of playing cause you're balancing against your sump level, height in overflow, evap and ATO. When I converted from Dursos to get everything how I wanted ended up adjusting height of last baffle. Since then truly pretty much set and forget.

Oh that could be the issue then. I'm using a Rubbermaid as a sump until I take apart my other tank and move the sump. There's no baffle in this Rubbermaid so the water level is all over the place

The deapth that the water enters the sump can be an issue as well. How far does your drain pipe go under water in the sump? The water heights can make a big difference too, so I wouldn't worry too much about it until you get that other sump in place.
